Patented Feb. 11, 1930 UNITED STATES PATENT OFFICE JESSE G. KING, DAYTON, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO FRIGIDAIRE CORPORATION, A CORPORATION OF DELAWARE REFRIGERATIN G APPARATUS Application filed March 27, 1924. Serial N 0. 702,456.

The present invention relates to refrigerating apparatus of the type in which a mechanically operated refrigerator is provided, and

particularly to the construction of the cabinet and the pipe connections between the evaporator and the mechanical apparatus.

Refrigerators for ice cream or the like are usually placed behind'counters or in corners of a room. One of the objects of the present invention is to provide a refrigerator for ice cream or the like in which the evaporator and mechanical apparatus are readily ac cessible regardless in what corner the refrigerator is placed.

In carrying out this and other objects, the invention provides a food cabinet including the evaporator and food chambers, and provides a cabinet unit for the refrigerating machine which is placeable adjacent different walls of the food cabinet whereby the food cabinet can be placed in the corner of a room while the machinery unit can be located adjacent a wall of the cabinet which is remote from the corner so that the mechanism therein is readily accessible.

' The evaporator of the refrigerating apparatus is located Within the cabinet which is provided with insulating walls and a further object is to render the evaporator accessible by providing a removable insulating portion adjacent the evaporator.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings:

Fig. 1 is a plan View of the improved refrigerator cabinet showing the refrigerating unit located on one side thereof and showing another position of said unit with respect to said cabinet in dot and dash lines.

Fig. 4 is a sectional view taken on the line 44 of Fig. 1.

Fig. 5 is a sectional View taken on the line 55 of Fig. 1.

Fig. 6 is a sectional View taken on the line 6-6 of Fig. 1. t

Fig. 7 is a sectional view taken on the line 7-7 of Fig. 1.

Fig. 8 is a sectional view taken on the line 8-8 of Fig. 1.

Fig. 9 is a sectional view taken on the line 9--9 of Fig. 3.

Fig. 10 is a fragmentary perspective view of a corner of the refrigerator cabinet with the top, end, and side covers removed.

y invention comprises a fixture for stores and the like, which is adapted to be installed in either a right hand or left hand corner. By the terms right hand corner and left hand corner is meant such corners as occur at both ends of a wall of a rectangular room or counter. That is, a corner may be termed a left hand corner when it is to the left of, a person facing perpendicularly the main side of the wall or counter having the corner. Conversely, a corner at the right of such a person is termed a right hand corner.

The fixture for stores or the like, herein referred to, may be rectangular horizontally, and may comprise a food compartment section alongside of a machinery compartment section. This fixture is adapted to be installed in either a right hand or left hand corner with the machinery compartment section away from the corner, and with the refrigerant connections away from the fixture Walls adjacent the corner, for the purpose of allowing ready access to these parts.

As one embodiment of my invention these sections may be made separable, thus allowing the fixture to be assembled and installed with the machinery compartment section away from the corner. The refrigerant connections are such that they are away from the fixture walls adjacent the corner. Thus, I may provide a food compartment section as a food cabinet or subassembly and the machinery compartment section as a machinery cabinet or subassembly.

The foregoing advantages are obtained even when the fixture is transferred from one corner to the other with its longitudinal dimension in its new position parallel to its longitudinal position in its original position.

Referring to the drawings, 20 is a food cabinet having a cooling chamber or unit 21 in which an absorber herein shown as an evaporator and food compartments 23 are placed. The cooling chamber contains a cooling medium (preferably a solution of alcohol and water) in which the evaporator and food compartments are immersed. The food compartments 23 are open at the top and are adapted to receive ice cream cans 24 (Fig. 5) or ice cream in brick form. Each food compartment is provided with a cover 25. The evaporator 22 is connected with a high pressure pipe 27 and a low pressure pipe 28 (see Fig. 3) which are suitably connected to the mechanical refrigerating unit 30, whereby the refrigerant is circulated through the evaporator 22. The entire mechanicalunit is enclosed in a cabinet 31 which is placeable adjacent different walls of the cabinet, and the construction of the cabinet is such that the refrigerant pipes 27 and 28 can be extended through different walls thereof.

Various locations of machine cabinet 31 are indicated at 31 in Fig. 1, and 31 in Fig. 2.

Referring more particularly to Fig. 10, the food cabinet includes an angle iron frame comprising horizontally extending end rails 35 at the top and bottom of the cabinet, horizontally extending side rails 36 at the top and bottom, and vertically extending posts 37. The ends of the rails and posts are mitred as shown in Fig. 10, and are joined at each corner by three gussets 38. The bottom rails carry slats 40 which in turn carry two plates 41 and 42 which are slightly overlapped to allow for variations in distance between the bottom rails 35. These plates cover substantially the entire bottom of the frame. The top rails support a wooden frame 43 to which the metallic tank 44, enclosing the cooling chamber 21, is secured. The tank 44 is insulated by bottom insulating wall 46, back insulating wall 47, front wall 48 and end walls 49 and 50. The insulating walls are sealed to the tank 44 by suitable compound such as hydrolene 51. Tank 44 is provided with a cover 52 which is secured with the tank to the frame 43 by nails or the like 54, there being a gasket interposed between the cover 52 and the tank 44 to prevent the scape of cooling medium. The cover 52 carries an insulating wall 56. To receive each food compartment sleeve 57, the wall 56 is provided with an opening 58 slightly larger in diameter than a bead 55 on sleeve 57, and the cover 52 is provided with an opening aligned with opening 58 and slightly greater in diameter than the main portion of the sleeve 57. The bead 55 rests to on the cover 52 and the bottom of sleeve 57 rests upon a wood block 59 supported by the bottom of the tank 44. The hydrolene 51 underneath the tank 44 is of substantial thickness to form a cushion for the sleeves 57. Each sleeve 57 is usually made of a soft material, such as copper, and in order to prevent said sleeve from being punctured due to the lowering of the ice cream can 24 therein, a steel disk 60 is provided in the bottom of the sleeve 57 against which the can 24 is adapted to strike when lowered. Hooks 61 are maintained within the sleeves 57 for lowering and raising the cans 24.

The construction herein shown illustrates a cabinet in which six food compartments are provided. It is to be understood that this number may be varied as desired. In the present construction five of the food compartments are provided with cylindrical sleeves, such as 57, for receiving cylindrically shaped cans 24 for bulk ice cream. One of the food compartments is rectangular in shape and comprises a sleeve 63 suitably soldered or otherwise secured to the cover 52, the opening in said cover being the same dimensions as the top dimension of the sleeve 63. The opening in the insulating wall 56 is the same as the openings for sleeve 57. An adapter 64 surrounds the opening in the cover 52 adjacent sleeve 63 whereby said opening 58 in insulation 56 may be made the same as the opening for the cylindrical sleeve 57.

The evaporator 22 includes a header to which pipes 71 are connected thereto in parallel. Header 70 is provided with a flange 72 with which said header is secured to the front wall of tank 44 and located concentric to an Opening 44 in the tank 44. .A ring 73 of substantially the same diameter as the flange 72 is located outside of the tank 44 and screws 74 extend through said rings 73 and into the flange 72 for securing said evaporator to the tank 44, there being gaskets 75 between the flange 72 and front wall of the tank and between said wall and the ring 7 3. Pipes 27 and.28 are connected through shutoff valves 76 and 77 to the header 70.

The Wood frame 43 carries a frame 7 9 including side walls 80 and 81 and a bottom wall 82. This frame is provided to inclose the shut-off valves 76 and 77 and the ring 73. The front of the frame 79 is closed by a plate 83 suitably secured to the walls 80, 81 and 82. The wood frame 43 is provided with a plug 84 attached to frame 43 by nails or screws 85. Plug 84 closes an opening in the frame 43 which provides the top wall of frame 79. Through the opening insulating material 86 such as ground cork may be inserted to completely insulate the end of the evaporator 22 and also prevent the ingress of air. Since no air can enter, condensation will not take place upon said end of the evaporar. Conduits 90, 91 and 92 extend lengthwise through the wall 48 from the frame 79 to the outside edge of the wall 48. These conduits are suitably sealed to theinsulating wall 48 by hydrolene as shown. The conduits provide passages for receiving ipes 27 and 28, and extend in a plurality of irections whereby said pipes may be connectedto the refrigerating apparatus 30. when said apparatus is placed adjacent different walls of cabinet 20. The cabinet 31 for the apparatus 30 is shown mounted upon the right side of the cabinet 20 and therefore pipes 27 and 28 extend through conduit 92. Conduits which are not in use, such as 90 and 91, are filled with an insulating material 93, preferably a mixture of ground cork and paraflin. Likewise, insulating material 93 is packed on the conduit 92 and around pipes 27 and 28 (Fig. 9).

The header is provided with an end cover 7 0 which supports within the header 70 a float valve for controlling the flow of refrigerant. It is therefore desirable that the cover 70* and the shut-ofi' valves 76 and 77 carried thereby remain in the position shown regardless of the direction from which pipes 27 and 28 extend. Therefore, in order that the pipes 27 and 28 need not be bent too abruptly if brought out through e ther of the conduits 90 or 91, the conduit 90 is located a substantial distance below the conduit 92, and conduit 91 is located slightly to one side of the shut-off valves. In Fig. 3, the locat ons of pipes 27 and 28 in different installations is shown by the dash lines 27 and 28 or 27 and 28 The cabinet 20 is provided with a wood top wall 97 attached to frame 43 by screws 96. A metal cover 98 of noncorrosive metal such as Monel metal covers the wall 97 and the screws 96", and is provided with sides 99 by which the cover is nailed or screwed to the wall 97.

In order to fill the tank 44, the top wall 52 is apertured to receive a sleeve 94 extending through the insulation 56 and sealed by hydrolene (Fig. 8). The sleeve 94 is closed by a plug 95 engaging the inslde wall of sleeve 94 which prevents fumes from the cooling medium entering between the top 97 and frame 43. The top 97 has an openin 1n align ment with sleeve 94 and is closed y a plug 96 which rests upon metal cover 98.

The top 97 is provided with openings'in alignment with sleeves 57, the cover 98 being flan ed at 100 to line each of these openings. Eac opening receives one of the food compartment covers 25.

The refrigerating apparatusis controlled automatically whereby the apparatus is started and stopped in accordance with the temperature within the cooling chamber 21. The control includes a thermostatic bulb 101 whichis immersed in the cooling medium within the tank 44. The thermostatic bulb is adapted to be inserted through either of two openings 102 or 103. Openings 102 and 103, as is clearly shown in Fig. 7, extend through the tank cover 52 and the insulating wall 56. The thermostatic bulb 101 is connected with a pipe 104. The wall 97 is provided with a groove 105 and the wood frame 43 is provided with a groove 106 which is adapted to receive the pipe 104. The top 97 therefore conceals the pipe 104. If hole 102 is not used to receive pipe 104, it is plugged. If the pipe 104 extends through hole 103 after the thermostatic bulb 101 has been placed in position, a stopper 108 notched to receive the pipe 104 is inserted in hole 103 to prevent the escape of cooling medium from the tank 44.

The apparatus cabinet 31 includes a frame which is constructed substantially the same as the angle iron frame of the food compartment 20 and includes top and bottom end rails 110, top and bottom side rails 111, and posts 112 secured together by gussets 117. The angle iron frame carries a wood frame 113 substantially the same height of the wood frame 43 of cabinet 20. A top 114 of wood is secured by screws 69 to the frame 113 and carries a metal top 115 of Monel metal or the like, the ends of which are bent down as at 116 for receiving nails or screws by which it is secured to the top 114. A drip pan 118 is secured to the bottom of the angle iron frame by the gussets 117.

A unitary structure including a motor 120, a compressor 121 and a condenser 122 is carried by the bottom rails 111. Horizontally extending angle irons 123 are carried by the posts 112. Angles 123 carry drip pan ,124 which in turn supports a compressor motor control 125 to which the pipe 104, leading from the thermo bulb 101, is connected. The control 125 is subjected to the pressure within the bulb 101 and is adapted to make and break the circuit of the motor for starting and stopping the compressor. The control mechanism is substantially the same as that shown in the patent to Bechtold and Mellowes, N umber 1,478,421, patented Dec. 25, 1923. This control is adapted also to render the motor inoperative when the pressure of the water from themain, which is used for cooling the condenser 122, is below a predetermined amount. Water for the condenser enters through pipe 130 which leads to a pressure element in the controller 125 for operating the motor switch. Pipe 131 leads from this pressure element to the condenser 122. Pipe 134 is the water outlet. In case the connections of the pipes 130 and 131 at the controller 125 shouldleak, the water will be caught by pan 124. Pipe 132 drains from pan 124 to pan 118 which is drained in any suitable manner. It will be noted that the drip pans 118 and 124 do not extend entirely across the length of the cabinet. Therefore, all the pipes which lead to and from the controller 125 and the condenser 122, and pipes 27 and 28 which are connected with the evaporator tend through the space not covered by drip pans.

A groove 139 is provided in frame 113 which is in alignment with the grom'e 106 of frame 43 of cabinet 20 and said pipe 104 passes through the groove 139 into the interior of the apparatus compartment 31 where it is connected with controller 125. A recess 135 is provided in the top of frame 43 and in the top of frame 113. These recesses extend around both of the cabinets and are adapted to receive the flanged ends of side panels 136, and front panel 138. The end panels 136 are interchangeable and can be placed at either end of the cabinet. The posts 37 at both ends of the cabinet 20 and the posts 112 of the cabinet 31 are each provided with aligned holes adapted to receive bolts 140 whereby the cabinet 31 can be secured adjacent either end of cabinet 20. It may be the case that the cabinets 20 and 31 do not fit closely together, therefore a sealing strip 141 is placed in the recesses 135 between the cabinets which will prevent water, dirt. etc., from falling between the cabinets and entering the machine cabinet 31.

The grooves 105 and 106 which extend to the right (in Fig. 1) of hole 103 and similar grooves 105 and 106 which extend to the left from the hole 102 are located midway between the front and back of the cabinet 20 so that when the cabinet 31 is located at 31*, the groove 139 will be aligned with grooves 105 and 106 to receive the pipe 104. Grooves 142 and 143 are provided in the top 97 and frame 43 (see Fig. 3) which lead to the opening 103 and are adapted to receive pipe 104 when the cabinet 31 is located below cabinet 20. In that position the thermostatic tube passes through conduit 91 and frame 79 as indicated at 104 in Fig. 3.

Since the cabinet 31 can be placed at either side. of cabinet 20, the refrigerator can be placed in substantially any corner of a room and ready access may be had to the side of the mechanical unit 30 and to the evaporator 22. Cabinets 20 and 31 are each provided with one interchangeable end panel 136. If it is desirable to place the refrigerator in a certain corner of a room, the food cabinet 20 should be placed against a wall of the corner and the front of the cabinet should facetheroom. Onepanel136 is placed on that wall of the cabinet which is adjacent the wall of the room and the machine cabinet 31 can be placed at the other end of cabinet 20 with the other panel 136 on the outside. By removing the panel 136 of the machine cabinet 31 access may be had to the side of the refrigerating unit, for the ready repair thereof. Likewise by removing front panel 138, plate 83, and insulation 86 ready access may be had to the valves 7 6 and 7 7 whereby the refrigerant line 27 and 28 can be shut off, the evapoexthe rator end wall removed, and the evaporator 22 can be unfastened from the tank 44. The thermostatic bulb can be inserted through eitheropening 109 and 103 according to which end of cabinet 20 the cabinet 31 is placed.

If it is desirable to place the cabinet 31 in the basement, the panel 136 thereof can be removed and applied to one end of cabinet 20. \Vhen the cabinet 31 is placed in the basement the refrigerant pipes .27 and 28 and thermostatic pipe 104 extend through conduit 91.

The evaporator 22 and sleeves 57 and 63 are readily removable. In order to remove same it is necessary only to remove cover 98 and wall 97. Then sleeve 57 can be removed. After the sleeve is removed and the nails 54 are renamed. the tank cover 52 can be removed and the evaporator can then be withdrawn.

The thermostatic bulb 101 is also readily removable. After the cover 98, top 97, and and plug 108 are removed, the bulb 101 can be withdrawn from the tank 44. By arranging the grooves 139 in top 114, the grooves 106 in frame 43, and the groove 105 in top 97 as shown in Fig. 5, the pipe 104 can extend underneath the cover ends 99 and over the tank cover 52, thereby eliminatin holes or notches in parts 99, 116, and 44 for the pipe 104.

Cabinet 31 is the same height as cabinet 20 and provides, when attached to cabinet 20, a substantially continuous counter therewith upon which ice cream buckets or dishes may be placed when being filled.
